Active clinical trials for "Hyperkinesis"

The study will examine the effect of a probiotic supplement (Lactobacillus helveticus R0052 and Bifidobacterium Longum R0175) dissolved in a dairy product such as milk or ice-cream on symptoms of ADHD and anxiety in children. The main goal is to determine if probiotics might be useful as a treatment for anxiety and ADHD symptoms in children. A second goal is to examine the effects of probiotics on saliva cortisol levels. Finally, the investigators are also interested in the effects of the probiotics on children's digestive health.

Previous studies using transcranial magnetic stimulation (TMS) with paired pulse protocols have shown that a conditioning TMS pulse applied to the human motor cortex changes the excitability of motor pathways from the motor cortex to spinal motorneurons. These effects depended on the stimulus intensity of both conditioning and test pulse and also the ISI). A characteristical sequence of inhibition (short interval cortical inhibition [SICI], GABA-Aerg), facilitation (intracortical facilitation [ICF]), and inhibition again (long interval cortical inhibition [LICI], GABA-Berg) is thought to be physiologically involved in motor control. Previous studies have also shown that neuronal inhibitory motor circuits are also disturbed in ADHD which will be restored by using methylphenidate. In this study the investigators sought to investigate if methamphetamine abuse (from the same chemical class of medications) will alter such effects of methylphenidate.

This is an outpatient program for children and adolescents with bipolar disorders. The naturalistic approach of the program will allow a proper investigation of the disorder, assessment of environmental and biological factors, the conduction of treatment studies, and follow-up of the subjects.

The purpose of this study is to investigate how emotional and non-emotional regulation processes differ in EIP patients (with different levels of ADHD symptoms/ADHD-comorbidity) compared to controls. The investigators will test these participants' abilities to regulate emotional and non-emotional processes, reward anticipation and reward receipt while they undergo functional magnetic resonance imaging (fMRI). The participants' motor inhibition capacity on a behavioral level will also be investigated. The hypothesis is that EIP patients will present with more deficits in emotion regulation processes compared to controls, even when controlling for ADHD symptoms. It is also hypothesized that higher levels of ADHD symptoms will correlate with dysfunctional non-emotional regulation processes, on a behavioral as well as brain mechanistic level.

The aim of this study is to analyse thanks to eye tracking experiments ocular movement classical parameters in children with attention deficit hyperactivity (ADH) and to compare them to results obtained in healthy children and to results obtained with neuropsychological tests commonly used in standard health care. We should then be able to compare eye tracking with neuropsychological parameters. The final objective is to give to health professional a tool for ADH investigation with which they should be able to do a simple and effective follow up of children with ADH.

ADHD is a neurodevelopmental disorder characterized by symptoms of inattention and / or hyperactivity-impulsivity that affects nearly 6% of school-aged children and persists into adulthood. More and more studies are interested in biomarkers of this pathology. The oculomotricity, which allows to highlight deficits motor and attention present in ADHD, is used routinely in the expert centers. In general, the pharmacological treatment of ADHD is associated with a clinical response in approximately 70% of cases. Today, there is no review to predict the individual response to treatment. Hypotheses The investigators hypothesize that a precise analysis of the oculomotor markers will allow to measure the improvement of the symptomatology of the ADHD disorder following the introduction of the psycho-stimulatory treatment. In other words, the investigators hypothesize that these markers could be a useful aid in patient follow-up by the clinician and allow early identification of responder and non-responder patients. Primary objective The main objective of this study is to measure the added value of oculomotor examination in the follow-up of psycho-stimulant-treated ADHD patients. Main Evaluation Criteria The primary endpoint is oculomotor performance. Parameters analyzed for each saccade are latency, amplitude, duration, average speed, direction. Secondary Criteria Evaluation (s) Correlations will be established between oculomotor data and scores obtained at the clinical scales assessing ADHD symptoms of inattention and hyperactivity as well as cognitive performance. The data obtained before the introduction of the psycho-stimulant treatment (V0, baseline) will be compared with those obtained after acute administration of methylphenidate (10 mg orally,V1) and during the follow-up visit at 6 months (V2).

The aim of the iSPOT-A study is to: identify brain, genetic and cognitive markers of Attention Deficit/Hyperactivity Disorder, and identify brain, genetic and cognitive markers that predict treatment response to short-acting methylphenidate in children and adolescents diagnosed with Attention Deficit/Hyperactivity Disorder.

Among children, attention-deficit/hyperactivity disorder (ADHD) is associated with an increased risk for accidents, especially bicycle and pedestrian (Leibson 2001; Jensen 1988; DiScala 1998). Anywhere from 40% to 80% of children diagnosed with ADHD continue to display symptoms of the disorder into adolescence(Barkley 1990; Gittelman 1985). Adolescents with ADHD are also at an increased risk for driving-related accidents, being 2 to 4 times more likely to experience a motor vehicle accident (Barkley 1993; Barkley 1996; Cox 2000), 4 times as likely to be at fault in the accident (Barkley 1993), and over 3 times more likely to incur associated injuries as a result of the accident(Murphy 1996). Stimulant treatment with immediate-release methylphenidate (IR MPH) has been demonstrated to improve driving performance in adolescents with ADHD. Hypothesis to be Tested: Main study: Just as stimulant medication improves simulation and on-road driving performance of ADHD teenagers, it is hypothesized that stimulant medication will improve routine driving performance. Substudy - Extended wear (15 hours) of Daytrana will lead to safer driving late in the evening (22:00 and 01:00), when the most dangerous driving mishaps are most likely to occur, and the next morning at 09:00.

The main purpose of this study is to evaluate changes in brain functioning using an MRI machine following mindfulness meditation training.

It is difficult to offer kids who live in rural areas good psychiatric care. There are only about 7000 psychiatrists for kids (pediatric psychiatrists) in the entire country. When adding nurse practitioners who specialize in mental health care for children, there still are not enough for everyone who needs care. This means either delays in treatment or no treatment at all by these important specialists. The purpose of this study is to explore how the investigators might offer psychiatric care to kids who live in rural areas through the use of telepsychiatry (TP), specifically those with attention deficit/hyperactivity disorder (ADHD). TP is a way for a physician to talk to someone in a remote area using a computer. The investigators will split the subjects into two study groups. As subjects are identified, they will be assigned a screening number according to a randomization table. The investigators will use TP for one group and face-to-face (F2F) care for the other group. The computer will allow the physician to look at and talk with the child and their parent(s). The investigators would like to know if TP is as good as, or nearly as good as F2F care, so the only difference in treatment approach between the two groups will be whether the subject is receiving treatment through TP or F2F care. Treatment is standardized using a flow chart called the Children's Medication Algorithm Project (CMAP) algorithm. The CMAP algorithm is a guideline established by a large number of experts who have agreed on the best approach to treatment based on scientific evidence. If TP proves as good as F2F care, it would help many parents and their children who do not live in or near a large city. The investigators will find study subjects when parents seek care at clinics in rural Oregon. The physicians in those locations will be aware of the study and will tell us when they think someone needs specialized mental health professional (either a pediatric psychiatrist or nurse practitioner with extensive experience in pediatric mental health). The investigators will make sure that ADHD is the right diagnosis using special exams that have been well-tested to show that they are reliable. The first visit-the intake visit-will probably take about an hour. At that visit, mental health professional will determine whether or not the patient is a candidate for the study. If the patient agrees, they will be asked to sign consent and child assent. The parent and child will then be given an exam that will confirm the diagnosis of ADHD. If confirmed, subjects will then learn if they have been assigned to the TP group or the F2F group and will be assigned to the treating mental health professional. In addition to the DISC, after consent the parent will be given several study instruments to take home with them. They will take about an hour altogether to complete. The first visit with the treating mental health professional will take about one hour and the three following visits will take about 30 minutes each. These visits will be about six weeks apart. At the third follow-up visit-the final visit-the parents will be again asked to complete the instruments they completed after consent and will be asked to complete a brief questionnaire that will give them the opportunity to describe their satisfaction or dissatisfaction with the treatment and care they received. Teachers will be asked to complete the Conner's 10-Item Global Index for the subject twice over the course of the study. The parent of the subject will present the scale to the teacher and retrieve the scale in a sealed envelope to return to the clinic. The diagnosis for ADHD will be made using an exam called the Diagnostic Interview Schedule for Children Version IV (DISC IV). This is a 90-minute exam that is done with a computer that helps you know what questions to ask and helps record the responses. The parents will also be asked to complete a few instruments and surveys that help us understand how well treatment is working. The investigators expect these exams to take about half an hour to complete. They contain questions about the subject's behavior and are completed by parents, except one brief instrument that the investigators will ask and teachers to complete before each follow-up visit. These instruments take about 10 minutes each to complete. This is an initial "pilot" study, so the information collected will mainly offer a better understanding of whether or not a larger study is possible. The investigators will look at how many subjects stayed in the study or dropped out and when they dropped out. The investigators will also look at the exams, scoring them to help us understand if those who were part of the TP group did as well, or nearly as well, as those in the F2F group.
